I mostly always attack. Unless of course i'm in a boss battle. Depending how far in the game i am, i will use GF's or Aura. I try and stay away from using magic due to it usually being junctioned to something, well, all the decent magic anyway.

Normal battle's i just attack, or draw if the enemy has a decent magic.

Mind you, i haven't played this game for some time, and am actually thinking about downloading it from the PSN after recently completing FF7 and 9

I always use Attack on normal battles and normally only attack with GFs on boss battles. I never use attack magic, I leave it untouched for junctioning. The items I use the most are recovery items. I never use stones.

spells dont really do a lot of damage in this game, even if you have a high magic stat so I just use the attack command most of the time unless I need to heal or its a boss battle and I may need the odd attack spell or support or debilitating spell sets
